Methods: Following an observational design, 1820 elderly dwellers of Birjand aged ≥ 60 years residing in urban or rural areas were explored. Data on the target NCDS and socio-demographic features, health behavioral factors, and objective assessment of height and weight were collected using interviews.

Results: The prevalence of hypertension, diabetes mellitus, chronic obstructive pulmonary disease (COPD), stroke, and cancer was 55.2% (1004/1819), 25.5% (463/1819), 1.0% (18/1807), 4.4% (80/1810), and 1.8% (33/1816), respectively. There was no gender difference concerning the prevalence of COPD, whereas the prevalence of hypertension, diabetes mellitus, and cancer was higher in women than men. Stroke was conversely higher in males than females. The common correlations of the five main NCDs were locality of residence and low body mass index (BMI). Rural residents had higher odds of diabetes mellitus and hypertension and lower odds of stroke. Diabetes mellitus, hypertension, and stroke were associated with a low BMI. Gender, age, and occupation were found to be associated with some of the NCDs. Retired and housewives had more chance to have hypertension and diabetes mellitus than the unemployed elderly.

Conclusion: The findings demonstrated that hypertension, diabetes mellitus, and stroke are the three prevalent NCDs among elders in the area and warrant a specific focus on reducing the burden of diseases and aligning healthcare services to prepare the whole needs of this population.
